Why can't we define re-assignable const reference variable?

[none]

Actually we can rebind already: this is legal code accepted by the DMD compiler

for (i = n; i-- > 0; ) {
  const B b = getConstB(i);  // are we rebind here n-times already?
  b.doSomething();
}

// the trouble is I cannot use the last 'b' i.e. getConstB(0),
// anymore, it will be out of scope
b.doSomethingElse();
